ROUGH-ROUNDING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters latent No. 463,967, dated November 24, 1891.

Application filed June 24, 1891. Serial No. 397,302. (No model.)

To all whom it may concern.-

Be it known that I, HENRY BRIGGS, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Rough-Rounding and Channeling Machines, of which the following is a specification.

My invention relates to improvements in machinery to rough-round and channel boot or shoe soles while upon the shoe and with the last in or out of the shoe. I attain this object by the device shown in the accompanying drawings, in which Figure 1 shows a front elevation of my mar5 chine as in operation, with the feed-clamp 1 forward (toward A) and locked and the fourmotion drop-feed 45 also forward toward A; Fig. 2, a detail of throat-plate and gage 15,feedclamp 1, and four-motion drop-feed 45 in front elevation, the solid lines showing themlocked in contact, as in Fig. 1, the two latter being forward, (toward A,) the dotted lines showing the two latter back (toward B) with the fourmotion drop feed 45 down; Fig. 3, a vertical 2 5 transverse View of throat-plate and gage 15,

C D looking from B toward A of Fig. 1; Fig. 4, an end view of Fig. 1 looking from B toward A of Fig. 1; Fig. 5, a vertical transverse section on line E F of Fig. 1 looking from A toward B of Fig. 1; Fig. 6, an end View of Fig. 1 looking from A toward B of Fig. l, omitting parts 15, 20, 24, 44, 46, and at; Fig. 7, a vertical transverse section of the fore part of a shoe while being rough-rounded and chan- 3 5 neled in this machine, looking fromA toward B of Fig. 1; Fig. 8, a detail of throat-plate and gage 15, sliding pin 1O6,'feed-c la1np 1, and four-motion drop-feed in front elevation, the solid lines showing the feed-clamp 1 drawn back toward B, the four-motion drop-feed 45 also down and back, (toward B,) the dotted lines showing the two latter fed forward toward A, with the four-motion drop-feed 45 also up. 45 Similar letters and figures denote similar parts throughout-the several views.

This machine is designed to rough-round and channel boot or shoe soles while upon the shoe, and with the last either in or out of the shoe, While the work operated upon is being automaticallyfed through the machine.

In previous machines of this class the feed movement has been defectivein its operation in some parts of the process. For instance, when the sole operated on has no material in places outside of the cut made by the edge trimming or oscillating cutting-blade the four-motion feed-blade or feed-awl heretofore used will not have any material to enter, and consequently will not be able to feed the sole 6o operated upon forward or against the edgetrimming or oscillating cutting-blade and channeling-knife, necessitating this feeding being performed by hand. By my invention this mechanical defect is overcome and the shoe and sole are fed forward automatically to the channeling-knife 72 and edge-trimmer or oscillating cutting-blade 89 by a positive feedmotion 45 and feed-clamp 1. The principal objects to be attained in this part of the process of the manufacture of boots or shoes are that the edge of the sole operated upon shall be rough-rounded to an equal and uniform width from the inseam, and that the channel shall be out at any varied distance 75 desired from the rough-rounded edge of the sole, as in the shank the channel is required to be at a greater distance from the roughrounded edge than in the fore part of the sole.

My invention consists of a frame carrying a main rotating shaft a,having upon it hubs or cams b 0 (Z to correctly actuate the various parts of the machine to feed, roughround, and channel the soles of boots or shoes while upon the boot or shoe and with the last in or out of the boot or shoe. A vertically and horizontally adjustable channeling-knife 7 2, having a vibratory motion, is supported and operated by the knife holder or carriage 73, mounted on and supported by 0 the upper part of the vibrating arm 86. This channeling-knife 72 and its holder or carriage 73 and vibrating arm 86 are vertical, or nearly so, and supported by the pivot'or fulcrum 77 as a center. This vibratingchanneling-knife 5 "2 and its holder or carriage 7 3 are mounted on the vibrating arm 86 and are capable of being raised and lowered by the screw-thread and adjusting-screw 76 to cut the channel in the sole to the depth required. The vibrating arm 86 is mounted on the slide-block 78 by its pivot or fulcrum 77 extending into the slide-block 78, which extends through the grooved block 79, permitting lateral adjustment of the slide-block 78 and channelingknife 72 to the required distance from the edge of the sole to be channeled. The groove for the slide-block 78 is cut in the rigid part or standard 116 of the frame of the machine. The slide-block 78 carries a stud 92, which is embraced by the slot 91 in thehand-lever 93, pivoted at 94 to a rigid part of the machine, so that the slide-block 78, vibrating arm 86, knife holder or carriage 73, and channelingknife 72 maybe moved laterally by the handlever 93.

The slide-block 78 is a T-shaped piece, the arm 79 containing two stop- screws 96 and 97, screw 96 screwing through arm 79 and stopping against arm 08 of plate 95, the other screw 97 passing through arm 79 of slide-block 78 and screwing into arm 98 of plate 95 to regulate the lateral adjustment of the slideblock 7 S, vibrating arm 86, knife holder or carriage 73, and vibrating channelingknife 72.

A bracket 80, attached to the lower part of the frame of the machine, supports a rockshaft 105, pivoted in two lugs 81 and 82 of the bracket 80. One arm 115 of this rockshaft 93 carries a cam-roller 85, geared into the groove 84 of the cam-wheel b. The other end 118 of the rockshaft 105 carries a swivelblock 126, geared into a slot 107 in the vibrating arm 86, vibrating this arm 86 on its fulcrum or pivot 77.

The part of my machine intended for roughrounding the sole at the same time that the channel is being out consists of the oscillating cutting-blade 89, having its cutting-edge parallel to its axis of oscillation and passing through the long slot forming the throat of the four-motion drop-feed 45, through the work, and through the throat or slot of the throatplate and gage 15, and operating,in connection with the edge of the throat of the throat-plate and gage 15, to form a scissorcut, separating or rough-rounding the sole as it is fed forward (from B toward A) bythe fou r-motion drop-feed 45 and feed-clamp 1. This throat-plate and gage 15 and feed-clamp 1 are connected by a pin or pivot 106, projecting from the side of the feed-clamp 1 and sliding in a slot in the throat-plate and gage 15, which permits a lateral movement also of the feed-clamp 1. My oscillating cutting-blade 89 is attached to a carrying-segment s, which is mounted to turn about the bolt 15, the head of the bolt acting against one side of the segment 5. This segment 5 and oscillating cutting-blade 89 are oscillated by the rack 21 at the end of a lever 22, pivoted at 23, a pin or roller 2;

entering a cam-groove 25 in the disk or cam c. The four-motion drop-feed 15 is attached to one arm 107 of a bell-crank pivoted at 108 to the upright portion of the feed-slide 50, the other end 109 of the bell-crank having a roller 110, bearing against the periphery of the cam 0, having a depression 111 to allow the feed end to drop at the proper time. The lower portion 50 of the feed-slide works in guideways g, attached to a rigid part of the frame of the machine, and has a stud h, geared in a slot in a lever 'i, one end of said lever i oscillating on a pivot or fulcrum 7, attached to a rigid part of the machine, the other end carrying a cam-roller e, gearedinto the groove 6 in the cam-wheel d. The upright arm 119 of the feed-slide 50 carries the swing-piece or lock-segment 4:4, pivoted at 48. Th is lock-segment 44 carries on its upper side the hand-lever 46 and feed-clamp 1. The throat-plate and gage 15 is pivoted at t on the rigid standard 116. The lock-segment at has on its upper end teeth 18, which gear into the pinion u, pivoted at w on the rigid part or standard 20, through which the pivot passes, and carries on its other end the ratchetwheel 24. The throat-plate and gage and feed-clamp 1 are pressed down on the work by a spring as, acting at one end against the hand-lever 46 and at the other end against the standard 20. The throat-plate and gage 15 and feed-clamp 1 act in combination as the gage for the work operated on, as well as forming a clamp with the four-motion dropfeed 4:5. The lock consists of the ratchetwheel 24, the two pawls 47 and 48, their pressure-springs a and y to operate in connection with them, and the cam-lever v, pivoted at 2 on the rigid part of the frame of the machine, this cam-lever t having a roll 13 geared into the cam-wheel (Z.

The work-support consists of two adj ustable rests 113 and 114, having slotted uprights, which may be adjusted to accommodate any style of round or flat boot or shoe sole, as different styles of lasts vary in their shape of bottom. The rest 113 has a flat surface on its upper end, which comes in contact with and supports the solo. The distance which the vibrating channeling-knife 72 projects above this flat surface gives the depth of channel required. The other work-support 114 has a roller at its upper end, the height of which may be adjusted to suit the pitch of any shape of sole operated upon.

In Figs. 1, 2, 3, 4, 5, 0, and 7 the solid lines show the position of the parts of the machine as in operation with the four-motion dropfeed up and forward, (toward A,) the throatplate and gage 15 and feed-clamp 1 also looked and forward, (toward A,) the oscillating cutting-blade 89 being up at the end of its stroke. The four motion drop -feed 45 then moves down and backward, (toward 13,) the lock of the feed-clamp 1 and throat-plate and gage 15 unlocks, and the feed-clamp lnext moves backward, (toward B.) The oscillating cuttingblade 89 now drops. At the same timethechanneling-knife 7 2 and its hand-lever 93 are in position for the channeling-knife 72 to commence cutting the channel at the proper distance from the edge of the sole in the shank, the dotted lines showing the position of the hand-lever 93 when adjusting the channelingknife 72 to cut the channel in the fore part of the sole.

The operation of this machine is as follows: To insert the work, the hand-lever 46 is pressed back (toward D) to the position shown by the dotted lines, thus raising the feedclamp 1 and throat-plate and gage 15, permitting the work to be inserted between the worksupports 113 and 114 and the throatplate and gage 15 and feed-clamp 1 until the inseam is against the edge of the two latter parts, the bottom of the sole resting on the guards or work supports 113 and 114. The hand-lever 46 is then released and forced by the spring 00 toward the solid lines, (toward 0,) pressing the feed-clamp 1 and the throatplate and gage 15 against the upper side of the sole of the boot or shoe operated on. The machine is now put in motion, the lock of the clamp-feed 1 and throat-plate and gage 15 now looks, and the four-motion drop-feed 45 now rises, clamping the work. The four-motion drop-feed 45 and feed-clamp 1 are next moved forward (from B toward A) by the feed-motion 50, carrying the work clamped between them from B toward A. The oscillating cuttingblade 89 now moves upward through the fourmotion drop-feed 45, and the sole is operated on, the throat-plate and gage 15 separating or rough-rounding the edge of the sole. The lock of the feed-clamp 1 and throat-plate and gage 15 next unlocks, the four-motion dropfeed 45 drops down, and its backward movement from Atoward B takes place, while the throat-plate and gage 15 with the work remain stationary. Next the oscillating cutting-blade 89 drops down, leaving the machine in the position it was in when the work was inserted. The spring 00 presses the hand-lever 46, so as to keep the feed-clamp 1 and throat-plate and guide 15 pressed down on the upper part of the sole and automatically adjusts them for any variation in the thickness of the sole operated on.

WVhen the machine is started, the vibrating channeling-knife 72 is also put in motion, actuated by the cam-wheel b, and continues to operate while the four-motion drop-feed 45, feed-clam p 1, and oscillating cutting-blade 89 are in action, the distance of the channel from the edge of the sole being regulated by moving the hand-lever 93. By a repetition of these motions the boot or shoe sole is rough rounded and channeled. When the operation is finished on the sole operated upon, the machine is stopped in the position described when ready to insert the work. The hand-lever 46 is then pressed back, (toward D,) raising the feed-clamp 1 and throat-plate andguide 15, releasing the sole, which is then removed from the machine, which is now ready for the insertion of the next sole to be operated upon.

If preferred, the pin or pivot 106 may be attached to the throat-plate and gage 15, and

pass into a slot in the feed-clamp 1, or it may be a loose pin or pivot orbolt passing through both parts 15 and 1, of sufficient length to permit the lateral movement of the feed-clamp 1, as previously described. I

In Fig. 3 at 89 I have shown a side view of my oscillating cutting-blade grooved on the upper side, an end View showing it, as at 89', atthe end of the face and sides for the purpose of removing the chips or waste material in sections in place of in a continuous strip as removed by a flat-edged oscillating cutting-blade which may also be used in this machine; but I prefer to use the grooved os- 2.
